The Lowdown

G’day, Rusty here. We’ve got a solid run of surf coming up at Jaconé, with plenty of variety across the next couple of weeks. The standout sessions are going to be later in the period, especially for the crew who can handle some size. Let’s get into it.

Friday morning, 21 August, kicks things off with a clean 5ft swell from the ENE, period of 8 seconds, and glassy conditions – that’s a beautiful way to start. The water temp is about average for this time of year, so no drama there. The combined swell energy is sitting at 405 (moderate), and with light offshore breezes, the waves will be peeling nicely. This is a solid, fun-sized option for intermediate surfers. Crowds can show up, but with those clean conditions, it’s worth the company for a wave.

Friday afternoon turns messy – the wind swings onshore at 22 mph, the swell drops to 3ft, and it’s a write-off.

Saturday, 22 August, is a write-off too. Onshore wind, bumpy, and the morning has a 5ft SSW swell (328 energy) with poor conditions. Afternoon jumps to 7ft but with a cross-onshore chop. Leave your board at home.

Sunday, 23 August, brings a much better picture. Morning sees a 6ft SSW swell (575 energy) with a 10-second period and cross-offshore winds – clean, lined-up waves. This is a good call for a morning session, but crowds are possible. Afternoon holds similar size (5ft, 522 energy) but with cross-offshore breeze, still clean.

Monday, 24 August, the swell picks up. A 8ft southerly swell (1690 energy – moderate to strong) hits in the morning, period of 13 seconds. That long period means the waves will have punch and good shape, but at beach breaks it can be a bit straight. The wind is cross-shore though, so there’s some chop. Afternoon jumps to 8ft (2797 energy – strong), 14-second period, but still cross-shore chop. It’s surfable for experienced surfers if you pick your peak, but not the best quality.

Tuesday, 25 August, morning is a beast: 10ft southerly swell (3269 energy – strong) with a 14-second period and cross-offshore breeze keeping it clean. That’s big, powerful, and only for experts – beginners and intermediates, stay out. The wind and tide are favourable, but the size is intimidating. Afternoon drops to 8ft (2570 energy) still clean with cross-offshore breeze.

Wednesday, 26 August, is the absolute standout of this whole outlook. Morning session: 8ft southerly swell (3272 energy – strong), 16-second period – that’s very long period groundswell. The wind is offshore from the ENE at 9 mph, making it glassy and clean. This is premium, heavy, powerful surf for experienced surfers only. It’ll be fast, deep, and make the paddle-out easier between sets. If you’ve got the skill, this is the one to circle on your calendar.

Thursday, 27 August, morning stays excellent: 7ft southerly swell (1620 energy) with 14-second period and offshore wind – still a top-notch session for experts. Afternoon gets a bit blown out with fresh cross-offshore breeze.

Friday, 28 August, cleans up again with a 4ft southerly swell (621 energy) and offshore wind in the morning – nice, clean smaller waves for the intermediates.

Saturday, 29 August, morning offers a fun 6ft ENE swell (675 energy) with offshore breeze – a bit shorter period at 8 seconds, but clean and punchy. Good for intermediates.

Sunday, 30 August, is flat – 3ft from the E (107 energy) with cross-offshore wind. Not worth paddling out.

Monday, 31 August, morning back to life: 6ft ENE swell (585 energy) with gentle offshore wind – clean and fun for intermediates.

From 1 September, it drops off badly. Onshore winds, small, messy surf. Only 2 September afternoon sees a bigger 7ft SSW swell (942 energy) but with onshore wind – poor quality, kite-surfing setup if anything.

Then, 3 September, Thursday morning, surprise: 6ft S swell (952 energy) with glassy conditions – that’s a clean session for intermediates and above.

Friday, 4 September, morning: 6ft SSE swell (810 energy) with offshore wind – clean, solid, a good way to end the run.

Saturday, 5 September, morning: 3ft SSE swell (372 energy) with offshore wind – smaller but clean for a relaxed paddle.

All up, Wednesday 26 August morning is the clear king – big, clean, groundswell power for experienced surfers. Friday 21 August morning is the best fun-size option for everyone else.

Stay salty.
Rusty.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.

Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
